No Toil 1252 Pre-Oiled Dual-Stage Foam Air Filter for CRF450

The No Toil 1252 is a pre-oiled, dual-stage foam air filter designed as a direct OEM-fit replacement for Honda CRF450 dirt bikes. Handcrafted in the USA, this filter arrives perfectly treated with No Toil's patented Evolution Air Filter Oil and is ready to install straight out of the package — no additional oiling required.

Built from premium flame-laminated, dual-stage foam, the 1252 delivers superior engine protection and improved airflow performance over standard paper-style filters. The two-stage foam construction uses two different pore sizes to maximize dirt-trapping surface area, while the flame-laminated bond heat-seals both foam layers together (rather than gluing) for a stronger, longer-lasting filter that maintains maximum airflow under demanding conditions.

Key Features:

• Pre-oiled and ready to ride — precisely treated with No Toil Evolution biodegradable filter oil right from the factory
• Dual-stage foam construction — two different pore sizes trap even the finest dust particles for outstanding engine protection
• Flame-laminated foam layers — heat-sealed bond (not glued) provides maximum airflow and superior durability
• Reticulated foam design — increases dirt-stopping surface area and overall foam strength
• OEM-spec fit — meets original equipment dimensions for a precise, secure fit in the stock airbox
• Biodegradable foam and oil — environmentally responsible and easy to dispose of safely
• Rated for 40+ non-toxic washes — cleans easily with No Toil biodegradable foam filter cleaner
• Gloves included — for clean, hassle-free installation
• 1-year manufacturer's warranty
